在c#中获取鼠标位置

Question

如何获得鼠标位置？我希望它在屏幕位置方面.

我启动我的程序我想设置为当前鼠标位置.

Location.X = ??
Location.Y = ??

编辑:这必须在创建表单之前发生.

Answer 1

您应该使用System.Windows.Forms.Cursor.Position:"一个表示光标在屏幕坐标中的位置的点."

Answer 2

如果您不想引用表单,可以使用interop来获取光标位置:

/// <summary>
/// Struct representing a point.
/// </summary>
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
    public int X;
    public int Y;

    public static implicit operator Point(POINT point)
    {
        return new Point(point.X, point.Y);
    }
}

/// <summary>
/// Retrieves the cursor's position, in screen coordinates.
/// </summary>
/// <see>See MSDN documentation for further information.</see>
[DllImport("user32.dll")]
public static extern bool GetCursorPos(out POINT lpPoint);

public static Point GetCursorPosition()
{
    POINT lpPoint;
    GetCursorPos(out lpPoint);
    //bool success = User32.GetCursorPos(out lpPoint);
    // if (!success)

    return lpPoint;
}

Answer 3

Cursor.Position将获得鼠标的当前屏幕位置(如果您在Control中,MousePosition属性也将获得相同的值).

要设置鼠标位置,您必须使用Cursor.Position并为其指定一个新点:

Cursor.Position = new Point(x, y);

您可以Main在创建表单之前在方法中执行此操作.

Answer 4

要回答您的具体示例:

// your example
Location.X = Cursor.Position.X;
Location.Y = Cursor.Position.Y;

// sample code
Console.WriteLine("x: " + Cursor.Position.X + " y: " + Cursor.Position.Y);

不要忘记添加using System.Windows.Forms;,并添加对它的引用(右键单击引用>添加引用> .NET选项卡> Systems.Windows.Forms> ok)

Answer 5

System.Windows.Forms.Control.MousePosition

获取鼠标光标在屏幕坐标中的位置. "Position属性与Control.MousePosition属性相同."

Answer 6

要获得该位置,请查看OnMouseMove事件.MouseEventArgs将为您提供x和y位置...

protected override void OnMouseMove(MouseEventArgs mouseEv) 

要设置鼠标位置,请使用Cursor.Position属性.

Answer 7

   internal static class CursorPosition {
  [StructLayout(LayoutKind.Sequential)]
  public struct PointInter {
     public int X;
     public int Y;
     public static explicit operator Point(PointInter point) => new Point(point.X, point.Y);       
  }

  [DllImport("user32.dll")]
  public static extern bool GetCursorPos(out PointInter lpPoint);

  // For your convenience
  public static Point GetCursorPosition() {
     PointInter lpPoint;
     GetCursorPos(out lpPoint);
     return (Point) lpPoint;
  }

}

Answer 8

如果您需要获取表单区域中的当前位置（通过实验获得），请尝试：

Console.WriteLine("Current mouse position in form's area is " + 
    (Control.MousePosition.X - this.Location.X - 8).ToString() +
    "x" + 
    (Control.MousePosition.Y - this.Location.Y - 30).ToString()
);

虽然，通过实验发现了8和30个整数。

如果有人能解释这些数字的确切原因，那就太棒了 ^。

此外，还有另一种变体（考虑到代码在 Form 的 CodeBehind 中）：

Point cp = PointToClient(Cursor.Position); // Getting a cursor's position according form's area
Console.WriteLine("Cursor position: X = " + cp.X + ", Y = " + cp.Y);
